The curvature of the endotracheal tube conforms to the shape of the airway with the head held in the neutral position, and is easier to insert then if the tube was straight. This development, largely, is an accident.
1. Methyl anthranilate, also known as MA, methyl 2-aminobenzoate, or carbomethoxyaniline, is an ester of anthranilic acid. The chemical formula for this compound is C8H9NO2. Methyl anthranilate is a clear to pale yellow liquid with a melting point of 24Â°C and a boiling point of 256Â°.n ester is the product of a reaction between an alcohol and an acid, usually an organic acid.3 Methyl anthranilate is derived from the reaction of methanol and anthranilic acid.
Methyl anthranilate naturally occurs in the Concord grapes and other Vitis labrusca grapes and hybrids thereof, and in bergamot, black locust, champaca, gardenia, jasmine, lemon, mandarin orange, neroli, oranges, rue oil, strawberry, tuberose, wisteria, galangal, and ylang ylang.t is food-grade and can be used to protect corn, sunflowers, rice, fruit, and golf courses. Dimethyl anthranilate (DMA) has a similar effect. It is also used for the flavor of grape Kool Aid. It is used for flavoring of candy, soft drinks (e.g. grape soda), gums, nicotine products, and drugs.
